High blood sugar may help cancer cells hide from the immune system

Researchers discovered a possible way cancer cells hide from the immune system: they build a thick, sugar-rich coating around themselves. High blood sugar can strengthen this protective shield under conditions that resemble the environment inside tumors, with the protein HSF1 playing a key role. Blocking this process could make cancer cells easier for the immune system to recognize and destroy.
